INTEGRATED SCHEME CARGO AIRCRAFT WITH UNSWATABLE TAIL RAMP FOR LOADING AND UPLOADING LARGE-SIZE CARGO Russian patent published in 2018 - IPC B64C1/22 B64C25/02 B64C39/10 

FIELD: aircraft engineering.

SUBSTANCE: cargo aircraft of an integrated circuit with an unswatable tail ramp for loading and unloading a bulky cargo contains a central part of the body, the outer surface of which is formed by aerodynamic profiles, cargo compartment door, located behind the regular section of the cargo compartment and in the open position ensuring the loading and unloading of transported objects, lower tail part of the body is a ramp with its upper plane being an extension of the cargo floor plane and intended for moving cargo along it, chassis with the possibility of deliberately changing the angle of the cargo floor relatively to the plane of the airside and the influx, its external shape, set by the set of longitudinal sections, the angles of their installation, twist and thickness providing a smooth transition to the wing consoles and the distribution of the lift force along the wing span, close to the optimal elliptical law.

EFFECT: invention is aimed at reducing the aircraft weight for the transportation of large-size and large-scale products.
